I tried to take a photo, but he was too close for my 100-400 lens and couldn't focus on the show off guy. I did think of holding my 70D+100-400 with just 2 fingers, so the ladies would stick around, but I couldn'tLast weekend, I went out to the desert with the local natural history group and saw a huge guy with muscles on muscles, shooting with a big Nikon D4 + 800mm lens, holding them with just one hand ... obviously he was showing off to some of the ladies there, who were gushing with amazement about how he could carry all that weight with just one hand ... the guy saw me with my Canon 70D + 100-400 L IS and told me how inadequate it was for birding ... he recommended that I switch to Nikon and a big a55 lens like the 800mm, he said that 800mm was the minimum focal length required for bird photography ... when I told him that I cannot afford such equipment, he generously offered to give me his Nikon D4 for free, "as he already got the D4S in Kuwait" (all this happened in front of some nice looking women) but the moment the women went their way, this guy takes his Lexus 4X4 and disappears into the desert - needless to say, I still haven't got the D4I have to try REALLY hard no to tell people they are holding the lens "wrong", i.e, with 4 fingers ON TOP of the lens, not underneath.
A friend of mine does that (and it looks really stupid to me) but there's no way he's changing his technique because the 'right' way is uncomfortable for him. No matter how often I told him he gets a less stable grip, and the tendency of zoom rotation to tip the camera. Not being a snob, just trying to help - but I gave up.
Darn! When I saw the underlined part, I thought you linked a snapshot of this guy holding the camera+lens combo.
Next time, try to keep the ladies around until he fulfills his promise (oh, and take a photo!).
